Flea Market Find

[Greg H]

Here Is 1 of 7 insulators I picked up at a flea market here in Saskatoon SK, there were 7 in the bag none are mint but they were free, she said I could have them so she didn't have to take them home again. They have a light amber tint and say dominion on the side, about 4" tall, any idea how old they are anyone?

I'm gonna move this to the new Insulator category. I hope it's gets the attention it needs there.
I'd guess no earlier than 1930. It looks like a Hemingrey 42 but clear. Where's the amber? If it's very slight it may be a reaction of the glass to UV light over the years. Clear could turn a brown or purple while exposed to sunlight.
